... In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7520. An output voltage is created on the other side of the HCPL- 7520 optical isolation barrier. This single-ended output voltage is proportional to the motor current. Since common-mode voltage swings of several hundred ...

... C2). Although the application circuit is relatively simple, a few recom- mendations should be followed to ensure optimal performance. The power supply for the HCPL -7520 is most often obtained from the same supply used to power the power transistor gate drive circuit dedicated supply is required, in many cases it is possible to add an ad- ditional winding on an existing transformer ...

... HCPL-7520. The bypass capacitors are required because of the high-speed digital nature of the signals inside the HCPL-7520. A 0.01 µF bypass capacitor (C2) is also rec- ommended at the input due to the switched-capacitor nature of the input circuit. The input bypass capacitor ...

... Smaller sense resistance decreases power dissipation, while larger sense resistance can improve circuit accuracy by utilizing the full input range of the HCPL -7520. The first step in selecting a sense resistor is determining how much current the resistor will be sensing. The graph in Figure 18 shows the RMS current in each phase of a ...

... If the sense resistor is not located on the same PC board as the HCPL-7520 circuit, a tightly twisted pair of wires can accomplish the same thing. Also, multiple layers of the PC board can be used to increase current carrying capacity ...

... The only other require- ment is to shut down the drive before the sense resistor is damaged or its solder joints melt. This ensures that the input of the HCPL-7520 can not be damaged by sense resistors going open-circuit. 3. ISOLATION AND INSULATION 3 ...
